Contribute to a PHP OSS project using Cloud Development with Exo IDE, GitHub, AppFog

Recently I started series of lessons (tutorials) on YouTube about Web Application Development. I will base the lessons on Zend Framework, HTML5, CSS3, JavScript (ES5). I try to use ONLY Cloud Technologies.
In this blog post I will explain how to Participate in an Open Source Software Project (OSS) using only Cloud Based  Technologies. I also try to introduce the Mind Maps in the Software Development Life Cycle and Technical Presentations.
